add --enable-optimized=debug
This will use -Og with GCC/Clang instead of -O0, which should make
unittests run faster without (hopefully) breaking anything related
to debugging. This is primarily meant to Jenkins builds, where
debug info is rarely needed (backtraces for unittest crashes AFAICT).
This can be also used to make LO itself run faster when developing,
but I personally do not find it worth it (with Clang and full PCH
this makes starmath build take about 70% longer, although presumably
for non-PCH builds the relative increase will be smaller).
